Paradoxical worsening of clinical symptoms after the withdrawal of the causative drug was reported in several cases of DRESS syndrome. 3 Clinical features appear commonly 2 to 4 weeks after administration of the offending drug. Clinical presentation consists of cutaneous manifestations and visceral involvement. Several case reports of Lamotrigine-induced DRESS syndrome manifested fever, rash, lymphadenopathies, eosinophilia, and hepatitis. The latter is the most reported manifestation. The typical skin lesions consist of a morbilliform eruption, involving over 50% of the body, usually associated with facial edema and infiltrative lesions. Our case is unusual by its clinical presentation. To the best of our knowledge, this is the first case with purpuric edema of extremities with palmoplantar involvement. Previously, two cases of Lamotrigine-induced DRESS syndrome were associated with purpura. The first case developed purpuric lesions on ankles, knees, and buttocks. 4 Although, the second case, lesions were widespread with palate involvement (Table S1). 5 Severe cutaneous adverse effects caused by Lamotrigine were associated with rapid dose titration, concurrent valproic acid administration, and the history of an anticonvulsant-associated allergic skin reaction. 6 In our case, the concomitant intake and increase of Valproic acid dose may have worsened skin lesions. Valproic acid is an enzyme inhibitor that prolongs the half-life of Lamotrigine, elevates its serum levels, and potentializes cutaneous side effects. 7 Systemic steroids are indicated in case of visceral involvement including transamininase levels >5 times normal, renal involvement, pneumonia, cardiac involvement, or hemophagocytosis. 8 Systemic steroids were given to our patient because of the severity of skin lesions.
